ROAD-GRADING- ATTACHMENT FOR VEHICLES.

Specification of Letters Patent.

Patented May 25, 1909.

Application filed August 14, 1907. Serial No. 388,548.

To all whom it may concern:

Be it known that I, WINFIELD S. LIVEN- GOOD, a citizen of the United States, residing l at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Road-Grading Attachments for Vehicles, of which the fo lowing is a specification.

This invention relates to improvements in road grading attachments for vehicles; and my object is to provide a substantial arrangement of this character which may be readily placed upon or removed from the running gear of an ordinary farm wagon, and will successfully resist the strains imposed thereon while at work.

Referring now to the accompanying drawings which illustrate the invention: Figure 1 represents a side elevation of the running gear of a wagon rovided with my attachment, the near w eels of the running gear being removed. Fig. 2 is a plan view of the same. Fig. 3 is a detail plan view of my attachment. Fig. 4 is a central section on line IVIV of Fig. 3. Figs. 5, 6, and 7 are details employed in carrying out the invention.

The running gear of the wagon in the present instance, consists of front and rear axles 1 and 2, respectively, wheels 3 mounted thereon, fore and hind hounds 4 and 5 upon the front and rear axles, res ectively, a headblock 6 upon the front ax e, and a bolster 7 upon the. rear axle provided with vertical stakes 9.

My removable frame, which is V-shaped in plan view, consists of longitudinal side pieces 10, transverse pieces 11 12 and 13 connecting said side pieces, a floor 14 secured to pieces 11 and 12, and a short reach 15 secured to the transverse piece 13. The front ends of pieces are connected by a seat-support 16 and a plate 17 The front end of the frame is removably secured to the front axle and headblook 6 by the king-bolt 18, which extends through the forward end of reach and plate 17. The rear end of the frame is removably secured upon the rear bolster by a retaining-plate 19, which in turn is secured to bolster 7 by a air of U-bolts 20, provided with nuts 21, wliich latter are sufliciently loose to permit the retaining-plate 19 to be adjusted obliquely with the bolster and the rear axle, as hereinafter described.

Plate 19 has notches 22 at its ends through which stakes 9 extend and assist bolts in holding the plate parallel with the bolster and the rear axle.

23 designates a lever having a U-shaped forward end 24 fulcrumed upon a bolt 25 extending through the transverse piece 12. The lower rearwardly-extending portion 26 of said lever is pivotally secured to the forward end of the hind hounds by a bolt 27, end 26 being provided with a series of holes 28 so that it may be secured to hounds of different lengths. The rearwardly-extending upper portion of the lever is provided with a stud 29, adapted to engage any one of a series of holes 30 in floor 14, and thus hold the lever from accidental movement.

When it is desired to adjust the rear axle obliquely to the line of draft, so that the rear wheels will prevent the scraper-blade from pushing the vehicle sidewise, the opera tion is easily accomplished by swinging lever 23 to one side or the other according to the position it is desired to adjust the axle.

31 designates the scraper-blade which is adjustably secured to the downturned ends of a V-shaped bar 33 carried by a turntable 34, pivotally mounted upon a bolt 35, and provided with a series of holes 36. Bolt 35 extends upward through a brace 37 carrying a pin 38 adapted to engage any of the holes 3 6. This arrangement permits of the scraperblade being adjusted obliquely to the line of draft.

Brace 37 is secured to the rear portions of a pair of draft-bars 39 connected at their forward ends by a loop 40 loosely engaging a clevis 41, embracing the front axle to which it is pivotally secured by the king-bolt 18. The scraper-blade is adjusted vertically by a pair of links 42 loosely engaging a cross-bar 43 uniting the rear ends of the draft-bars 39. The upper ends of links 42 loosely engage a pair of crank-arms 44, fulcrumed upon bolts 45 and provided with cog-teeth 46, which intermesh with worms 47 on the ends of a shaft 48 carrying a pair of hand-wheels 49, whereby said shaft is rotated. By turning the shaft in one direction it is obvious that the scraper-blade 31 will be lifted from the ground, and by turning said shaft in the opposite direction the blade will be lowered.

The scraper-blade is adjusted laterally by a link 50loosely connected at one end to crossbar 43 and at its opposite end to a handlever 51 fulcrumed upon a pin 52, and provided with a latch 53 adapted to engage a notched segment 54, and thus lock the lever in any of its adjusted positions. Bolts 45 and 52 and segment 54 are secured to standards 55, four of the latter being employed to support the mechanism for adjusting the scraper-blade vertically or. laterally. Shaft 48 is journaled at its ends in bearings 56 uniting the upper ends of standards 55.

To remove the attachment from the running gear it is only necessary to remove bolts 20, 27, and king-bolt 18.

Having thus described my invention, What I claim is z 1. The combination With the running gear of a Wagon, of a removable frame mounted thereon, a scraper-blade suspended from said frame, means for pivotally securing the for- Ward end of the removable frame to the running gear, and a retaining-plate for securing the rear end of said frame to the running gear.

2. The combination with the running gear of a Wagon, of a removable frame mounted thereon, a scraper-blade suspended from said l frame, means for pivotally securing the for- Ward end of the removable frame to the running gear, a retaining-plate for securing the rear end of said frame to the running gear, and U-bolts for securing the retaining-plate to the running gear.

In testimony whereof I affix my signature in the presence of tWo Witnesses.
